It may happen that the purt to be lubricated, or some portion of the oilelianuel therein, or perhaps the bore of the nipple 65, may be elo ged.Under such Giri-uur stances. oil un er pressure is fed into the cup Gl.through the conduit 109. until the art 69 moves downwardly. the, spring82 einer compressed, and the vulve 71 cooperet` ing with the seat 64 toprevent oil from passing into the nipple 65 due to uessure exerted onthe retarder 7 8.
